Thirty years of child psychology: a selective review

A selective review of the literature in child psychology over the last 30 years reveals substantial changes in methodology, in analysis and the interpretation of findings. Evidence on the multifactorial nature of development is drawn from genetic/environmental research, longitudinal studies and a consideration of potential long-term effects of early experience, including planned intervention. It is increasingly recognized that individuals play some part in causing their own development, via ongoing transactional processes. Eight themes form the basis for discussion, including the belated emergence of Piaget's theory and the changing outlook for the mentally retarded. In addition, the explosion of research upon infancy and the growing influence of behavioural psychology are noted.
